Set the draw transparency for text and bitmaps
void PgSetTextTransPat( PgPattern_t pat );
void PgSetTextTransPatCx( PhGC_t *gc,
PgPattern_t pat );
ph
These functions set a masking pattern and applies it to text and bitmaps.
You should use it in combination with
PgSetTextColor*() or
PgSetTextDither*().
These functions use the same patterns as
PgSetFillDither*().
To disable transparency and draw normally, specify the
Pg_PAT_DEFAULT pattern.
|
Because of speed considerations, some graphics drivers don't
draw strokes with a transparency mask and, as a result,
ignore the stroke transparency pattern. |
PgSetTextTransPat() works on the current graphics context,
while you can specify the graphics context gc for
PgSetTextTransPatCx().
